00:00Hi kids! Today we will learn about transformations. That is, translation and scaling. So let's start!
00:13First of all, we will learn what is transformation.
00:18Transformation is any process which changes the position, shape, or viewing angle of any shape.
00:28There are different types of transformation depending upon the kind of change it's doing to the 2D shape.
00:37Let's learn more on it with the help of examples.
00:42Let's first learn first type of transformation, that is, translation.
00:50Transformation, where we move objects from one place to other place along a straight path, is called translation.
01:00We move this sign from position A to position B. So we say we translated this sign from position A to position B.
01:15So the task of translation is to move an object or shape from one position to the other without changing its shape and angle.
01:27Here we move this figure from one point to the other. Only the position of shape or 2D figure is changed.
01:37Let's see another example.
01:40Here we have a capital letter F. We have to translate this shape two squares up and four squares right.
01:51Remember, translation is always moving the object along a straight line like sliding.
02:00First mark the point where you want to move your shape to. Then make an arrow to that point.
02:08Now move your shape along the arrow you just made.
02:12Yes, we have now translated the figure two squares up and four squares right.
02:21Now let's learn another type of transformation, that is, scaling.
02:29Transformation, where we change the size of a 2D figure, is called scaling.
02:37Like we may double the size of a 2D figure or may make it smaller. This is known as scaling.
02:46Zooming in and zooming out are examples of scaling the objects.
02:53Example, here we increase the size of this figure. So we have done scaling operation on this figure.
03:03Also remember, if we increase or decrease each dimension of the figure equally, the object changes its size only, not shape.
03:16This is called even scaling.
03:20This is an example of even scaling, as we have increased the size of this figure, but not its shape.
03:31These are some more examples of even scaling.
03:35Here, each dimension of the figure is evenly scaled, that is, increased equally.
03:43Here, this figure is made smaller, but the shape is not changed, so this is even scaling.
03:50Here, the star is made bigger, but the shape is not changed, that is, each dimension is changed equally.
03:58Here, this is an example of even scaling.
04:02If we differently change the different dimensions of a figure, then the object is distorted.
04:08That is, the shape of the object is changed, and such scaling is uneven scaling.
04:16This is an example of uneven scaling.
04:20As here, we change the shape of figure along with the size.
04:24That is, not the same amount of change is made along each dimension of the figure.
04:32Here are some more examples of figures with uneven scaling.
04:37That is, along with the size, shape is also changed.
04:43Remember, in uneven scaling, each dimension of the figure is not equally scaled, or changed,
04:52so the figures are distorted, as a result of uneven scaling.
04:58So kids, today we learned two types of transformations on 2D figures.
05:05Translation, which is the same as sliding an object along a straight line.
05:12And scaling, where in even scaling, same as zooming in or zooming out, and uneven scaling,
05:21where along with the size, shape of object 2 is changed.
05:26Now you may go ahead and take a quiz to learn more.
05:30Bye-bye!
